EAsTENING DEVICE..`

To all whom'e't may concern: Y

Be it known that I, JAMES EDWARD PIERCE, a citizen of the United States, residing at Albion, county of Calhoun, State oflVIichigan, have linvented certain new andr useful Improvements in vFastening Devices, ofv

g which the vfollowing is a specification.

.I1-j fastening devices.

This 'invention relates to improvements in The objects of this invention are: First, to provide a-simple and effective fastening device for the end gates of dough troughs or vfor use in similar relations. Second, to pro'- Vvidean improved end gate' fastener having camineans by means `of which the gate 1s' forced to its s eat. Y v

Further objects, and objects relating to details and economies of construction Vwill Y definitely appear from the detailed descrip- 20 view of the end 0f a dough trough showing the end gate fastened in place by my improved .fastening device. Fig. II is a fr ag- J vmentary, detail, vertical, sectional. view through the end of thedough trough, shown in Fig. I. Fig. III is a view: similar to fFig.

II showing the end gate vreleased and held V ing. bar. Fig.V IV is a detail perspective`lr view of the locking bar showing the locking in'V open position by the handle of-"the lockcams and thehandle.

'In the drawing similar reference charac-v ters refer to similarparts throughout the several views, andthe sectional views are vtaken, looking in the directionof ther4 little arrows at the ends of the section lines.

Considering the numbered parts of thef drawing, the dough trough 1 has an opening inthe end thereof which is closed by the endl gate 2 hinged to the end ofthe dough* troughat. Fastened tothe .endgate are `U-shapedmembers l whichholdthe locking Vbar loosely in place as clearly appears in, Figs. II and III.l The locking bar 5 is long Aenoughso that it extends beyond the side'sof I Specieation of Letters Patent;

contemplate making the locking bar, handle and; locking cams 'all fromcne malleable casting.'

as provided with three locking cams, this is not necessary as one locking cam would be sufficient to do the work. fastening devices of the size which I contemplate using, two cams or more are desirable. I show my handle as bent at a right angle, but this is not essential as it might Ybe made in other forms or the U- shaped handle might be dispensed with and a simple arm on the lock bar substituted therefor. I have shown this fastening deviceras applied to use forfastening the end gate of a dough trough. VIt will be evident, however, that this fastening device is equally applicable for use as a fastener for the end gates of wagons or for similar uses and that it is capable of use as a fastening device generally. I, therefore, do not wish to be restricted to the use of this fasteningl device in the relation in which I have shown it but v IV desire to claim theV broadly. v i Y I am aware that the particular embodifastening device i nient'which I have here shown is susceptible fore, I desire to claim the saine specically as well asl broadly as indicated by my appended claims. f

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

l. In a fastening device, the combination with a closure hinged at its upper end, of a pair' of fixed keepers having upturned outer ends disposed at the sides of said closure, a locking bar, a pair of U-shaped locking bar retaining members carried by said closure and looselyV retaining said locking bai' for rotative and lateral movement, so that it may be engaged with and rocked upon said keepers or be lifted therefrom, locking cams fixed on saidV locking bar, and a handle for `However for said locking bar, said cams being positioned to beV actuated by the downward movement of said handle whereby the locking bai' may be engaged with the keepers and the cams actuated by a continuous downward move- -ment and the cams released and the locking 'loosely retaining said locking bar for rotative and lateral movement so that it may be engaged with said keepers or be disengaged therefrom, locking cams fixed on said locking bar, and a handle for said locking bar, said cams being positioned to be actuated by the movement of said handle away from the closure hinge whereby the locking bar may be engaged with the keepersand the cams actuated by a continuous movement and the cams released and the locking bar disengaged from the keepers and the closure opened by a continuous movement.

3. In a fastening device, the combination with a closure, of fixed keepers, a locking bar, locking bar retaining members carried by said closure and loosely retaining said locking bar for rotative and lateral movement so that it may be engaged with said keepers or disengaged therefrom, a cam fixed on said locking bar and a handle for said locking bar whereby it may be adjusted laterally to engage and disengage the same with said keepers and rotated to actuate said cam.

In witness whereof, lI have hereunto set my hand and seal in the presence of two witnesses.
